This study investigates a new type of high-performance coated sand as a petroleum fracturing proppant material. Modified quartz sand was coated with a layer of low-density resin to reduce the overall density of the proppant, thereby improving the suspension of the proppant in the fracturing fluid. Resins play an important role in the preparation of coated …

A major advantage of this approach is that there is less steam in the fill process that can otherwise fracture and destabilize the sand construct, or disrupt the pour. 2. Resin Sand. Resin sand, also referred to as resin-coated sand or furan sand, is a type of molding sand used in sand casting processes. Furan refers to the use of furfuryl ...
